What is the X Intercept Calculator?

X intercept calculator with steps is a tool used to determine the points where an equation intersects on the x-axis in a cartesian plane. Our tool simplifies the process of finding the given linear equation that helps in plotting a graph that crosses the x-axis in less than a minute.

X Intercept Calculator with Steps

The x intercept finder is a beneficial tool because when you do it manually, you may be stuck in its complex calculation, but using this calculator your workload reduces to minus because it gives you solutions to x-intercept problems quickly.

What is the X Intercept?

An x-intercept is the point on a graph that crosses the x-axis and the cartesian point y is zero at this point. This situation happens when the value of y becomes zero. These points are called x-intercepts, (x, 0) because the y-coordinate is zero at these points.

It is an important process that allows you to evaluate the points where the graph crosses the x-axis. Resultantly, it provides important information about the behavior of the equation.

What is the X-Intercept in y=mx+b?

The x-intercept is the value of x where the line crosses the x-axis. In the context of the equation y = mx + b, where m and b are constants that represent the slope and y-intercept respectively.

How to Calculate X Intercept?

For calculating the x-intercept from the given equation, the x-intercept calculator determines the points where the graph crosses the x-axis so that you know the behavior and roots of the slope equation. Let's break down the steps to calculate the x-intercept of a linear equation:

Step 1:

First, the x intercept solver starts with the equation of slope y = mx + b.

Step 2:

To find the x-intercept, suppose y = 0, because of the x-intercept, the graph crosses the x-axis.

Step 3:

Now, solve the equation for the x value as per the mathematical expression of the equation.

Step 4:

The x-intercept of the slope equation on the graph crosses the x-axis at the point (x, 0).

Find X Intercept - Example:

Some examples are given to understand how the x intercept calculator with steps calculate x intercept in some steps.

Example: What is the X-intercept of 2x+5y=10?

Solution:

To find the x-intercept of the equation 2x + 5y = 10, put y = 0:

$$ 2x + 5y \;=\; 10 $$

Put y=0

$$ 2x + 5(0) \;=\; 10 $$

$$ 2x \;=\; 10 $$

$$ x \;=\; 5 $$

Therefore, the x-intercept of the equation 2x + 5y = 10 is x = 5. The point of the slope of the equation is (5,0).

What are the X-intercepts of x^2-8x+16?

To find the x-intercepts of the quadratic equation x² - 8x + 16, follow some steps of the calculator to get points of the given equation.

Let y = x² - 8x + 16, Put y = 0

$$ 0 \;=\; x^2 - 8x + 16 $$

$$ x^2 - 8x + 16 \;=\; 0 $$

Solve the quadratic equation with the help of the factorization method.

$$ x^2 - 8x + 16 \;=\; 0 $$

$$ x^2 - 4x - 4x + 16 \;=\; 0 $$

$$ x(x - 4) - 4(x - 4) \;=\; 0 $$

$$ (x - 4)(x - 4) \;=\; 0 $$

$$ (x - 4) \;=\; 0 \; \; \; \; (x - 4) \;=\; 0 $$

$$ x \;=\; 4 \; \; \; \; x \;=\; 4 $$

Therefore, the quadratic equation x² - 8x + 16 = 0 has a single x-intercept at x = 4. The point of the slope of the equation is (4, 0).

Frequently Ask Questions

What is the intercept of f(x)= 25-5x?

To find the intercept of the function f(x) = 25−5x, we need to determine the values of f(x). As we know y = f(x). So, put y = f(x) in the given equation as,

$$ y \;=\; 25 - 5x $$

For x-intercept, put y = 0,

$$ 0 \;=\; 25 - 5x $$

$$ 25 - 5x \;=\; 0 $$

$$ 25 \;=\; 5x $$

Divide 5 on both sides,

$$ 5 \;=\; x \;OR\; x \;=\; 5 $$

Therefore, the x-intercept of the given function f(x) = 25 − 5x is equal to x = 5, and the points are (5, 0).

What is the positive x intercept of y=x^2-2x-3?

To find the positive x-intercept of the quadratic function y = x² − 2x − 3, follow these steps:

$$ y \;=\; x^2 − 2x − 3 $$

For x intercept put y = 0,

$$ 0 \;=\; x^2 − 2x − 3 $$

$$ x^2 − 2x − 3 \;=\; 0 $$

Find the quadratic equation root with the factorization method.

$$ x^2 − 3x + 1x − 3 \;=\; 0 $$

$$ x(x − 3) + 1(x − 3) \;=\; 0 $$

$$ (x − 3)(x + 1) \;=\; 0 $$

$$ (x − 3) \;=\; (x + 1) \;=\; 0 $$

$$ x \;=\; -1 $$

Therefore, the positive x-intercept of the function y = x² − 2x − 3 is x = 3 and x = -1 and the given equation points are (3, 0) and (-1, 0).

How to calculate the x-intercept of a rational function?

The Calculation of the x-intercepts of a rational function involves finding the values of x where the function f(x) equals zero. A rational function is typically expressed in the form:

$$ f(x) \;=\; \frac{p(x)}{q(x)} $$

Where p(x) and q(x) are polynomials, and q(x) ≠ 0. To calculate the x-intercepts of the rational function few steps should be followed. These are:

Step 1:

Find the values of x for which f(x) = 0 as y = f(x). This represents the x-intercepts because, at these points, the function crosses the x-axis.

Step 2:

Set the numerator p(x) of the rational function equal to zero to p(x) = 0.

Step 3:

Solve the equation p(x) = 0 to find the values of x where the numerator equals zero. These values are potential x-intercepts of the rational function.

What is another name for the x-intercepts of a quadratic?

For the x-intercepts of a quadratic function or equation, we use another name in mathematics roots or zeros.

Roots or Zeros:

Roots: This term emphasizes the points where the quadratic equation x² + bx + c = 0 intersects the x-axis, where y = 0.
Zeros: Similarly the roots term refers to the values of x where the quadratic function becomes zero.

The roots or zeros of a quadratic equation are crucial because they represent the solutions to the equation where the graph crosses the x-axis. In the quadratic formula x = b² − 4, these roots can be real or complex, depending on the discriminant Δ = b² − 4ac.

What is the discriminant if there is one x-intercept?

The discriminant of a quadratic equation is a process that is used to determine its roots (roots are real, distinct, or imaginary) in the x-intercept. For a quadratic equation of the form ax² + bx + c = 0, the discriminant Δ is given by:

$$ Δ \;=\; b^2 − 4ac $$

Here:

a, b, and c are coefficients of the quadratic equation.
b² - 4ac is the discriminant.

In x-intercept, the discriminant is defined as:

Two Real X-Intercepts:

If Δ > 0, the quadratic equation has two distinct real roots (x-intercepts).

One Real X-Intercept:

If Δ = 0, the quadratic equation has exactly one real root (x-intercept), which means the graph touches the x-axis at exactly one point (the vertex of the parabola touches the x-axis).

No Real X-Intercepts:

If Δ < 0, the quadratic equation has no real roots (x-intercepts). In this case, the graph does not intersect the x-axis.
